A method for monitoring a driver of a vehicle by means of a measurement system, wherein the method comprises the following steps:
- a) providing a sensor, wherein,
- at least one capacitors has at least two electrodes which are arranged in a horizontal direction along and on a flexible carrier material with respect to one another, at least one dielectric layers being arranged between the at least two electrodes, and the sensor has at least one further capacitors which is arranged in a transverse direction above or below the at least one capacitors and is arranged spaced apart from the at least one capacitors by a water-impermeable layer, so that a capacitor stack is formed, and both the at least one capacitors and the at least one further capacitors are constructed in the same way, and further wherein the at least one capacitors and the at least one further capacitors forming the capacitor stack perform the same tasks, and
- further wherein the measuring system comprises at least two sensors, in communication with a Central Processing Unit (CPU) wherein the at least two sensors are divided into groups of at least one sensor, functionally by the CPU, based on at least the following criteria:
- arrangement location of the at least two sensors on the carrier material, wherein the carrier material is divided into area regions, and within an area region only sensors of one group are arranged, wherein,
- at least one of the capacitors is arranged on a side facing away from the carrier material having at least one electrodes and/or the at least one dielectric layers, at least one at least partially liquid-permeable and/or liquid-absorbing moisture layers is arranged at least in places on a side of the at least one electrodes facing away from the carrier material and/or the at least one dielectric layers,
- the at least one electrodes and/or the at least one dielectric layers thus being arranged in a transverse direction between the carrier material and the at least one moisture layers so that a capacitance is at least partially changed by a liquid at least partially impinging on the dielectric layers, wherein
- a processing unit is set up and provided for measuring and/or storing the capacitance change, so that a capacitive humidity sensor is produced, wherein the sensor is additionally a capacitive pressure sensor, wherein
- the processing unit is additionally adapted and provided for measuring and/or storing a capacitance change of the capacitive pressure sensor caused by external pressure, and
- further wherein the capacitive pressure sensor is one in which the capacitance change due to the deflection of a membrane and the resulting change in a plate spacing is evaluated as a sensor effect, so that the membrane is the at least one dielectric layer or the at least one electrodes,
- b) providing at least one measurement system for measuring pressure and/or humidity, wherein the measurement system is coupled to at least one vehicle element or is installed with at least one in an integrated manner and the measurement system has at least one of the sensors for measuring a stress level of the driver such that the sensor measures pressure and/or humidity;
- c) subsequent forwarding of the pressure and/or humidity values, to the central processing unit (CPU) of the measurement system;
- d) detecting and recognizing a stress level of the driver based on the pressure and/or humidity values;
- and
- e) determining a selected action based on the pressure and/or humidity values as measured by the measurement system, wherein the action is selected from the actions consisting of:
- setting up a call to a remote support center, transmitting the stress level value to a remote support center, generating an audible alarm and generating a visual alarm, adjusting a volume of speakers in the vehicle, adjusting a seat position of a vehicle seat of the vehicle, and displaying break recommendations to the driver.
